Ahead of music's biggest night, we've rounded up everything you need to know -- from where to watch to who's performing to moments you definitely don't want to miss -- before the awards show on Feb. 15.

ET's Red Carpet Coverage: ET's Nancy O'Dell and Kevin Frazier, along with CSI: Cyber star Shad "Bow Wow" Moss, are hosting a 60-minute live red carpet show from the Staples Center in downtown Los Angeles for the first time ever. The special kicks off at 7 p.m. ET/4 p.m. PT on your local CBS affiliate station and CBS All Access.

What Time Do the GRAMMYs Start?: The telecast airs Monday, Feb. 15 at 8 p.m. ET/5 p.m. PT on CBS.

Who's Hosting?: LL Cool J is making his return to the GRAMMYs stage, marking his fifth consecutive year as the star-studded event's master of ceremonies. "It's going to be an incredible night and I'm excited to share this experience with the world," he said in a statement.

Who's Seated Next to Who?: Year after year, we always look forward to seeing where the stars will be seated. ET has learned that Selena Gomez, Taylor Swift, Jack Antonoff and Beyoncé will all be front row and center. Drake and Tori Kelly are in the same section just a few rows back, with Lady Gaga, Nicki Minaj, Justin Bieber, Chrissy Teigen and John Legend one to three rows to the left.

Notable Nominees: Rapper Kendrick Lamar leads the nominations pool, with a total of 11 nods. Taylor Swift and The Weeknd follow close behind him, each having received seven nominations.

Music newcomer Charlie Puth is nominated for the first time ever, receiving three nods for his collaboration with Wiz Khalifa on "See You Again."

Blake Shelton is up for his seventh career nomination in the Best Country Duo/Group Performance category for "Lonely Tonight" featuring Ashley Monroe. Even though he's never actually walked away with a golden gramophone, he's hoping it will go to country-bluegrass duo Joey + Rory.

Record of the Year vs. Song of the Year -- What's the Difference?: Song of the Year honors the songwriter(s), while Record of the Year honors those who recorded the song (i.e. the artist(s), producer(s), recording engineer(s), and/or mixer(s)).

Who's Kicking Off the Opening Number?: Taylor Swift will kick off the show with a tune from her GRAMMY-nominated album, 1989.

Who Else Is Performing?: Adele may not be nominated for any awards this year (her album, 25, came out after this year's eligibility period), but we already have a good feeling she's going to steal the show anyways! The singer will grace the GRAMMYs stage for the third time, performing a track from the record-breaking25.

For the first time in five years, a Broadway production is appearing on the show. The cast of the hit musical, Hamilton, will be performing live via satellite from the Richard Rodgers Theatre in New York City. "We're going to do the opening number from Hamilton," Ken Ehrlich, executive producer of the GRAMMYs, told ET earlier this month. "It's the toast of Broadway."

Special Tributes: This year's awards show will pay homage to some of the biggest music icons we've lost in the past year. Lady Gaga (with the help of music producer Nile Rodgers) is set to perform for the fourth time on the GRAMMYs, this time taking the stage to give an "experiential tribute" performance to David Bowie, who died on Jan. 10. "We had already booked Lady Gaga on this year's show, but when David passed -- almost in a single moment -- we knew we had to change direction," Ehrlich said in a statement. "We immediately spoke and agreed that she should be the one to honor David. She's perfect for it."

Members of the Eagles will come together once again as part of a "one-time-only special tribute" honoring their late bandmate, founder and guitarist Glenn Frey, who died last month at age 67. Their close pal and frequent collaborator, Jackson Browne, will join them on stage to perform an Eagles classic.

Chris Stapleton, Gary Clark Jr., and Bonnie Raitt will join forces to pay tribute to the late B.B. King, who died last May at the age of 89. The Recording Academy also has something special planned for the late Natalie Cole, who died last month at age 65.

Gwen Stefani's Live Music Video: Get ready to witness history! The No Doubt frontwoman is collaborating with Target to create the first-ever music video created on live television. Stefani will be shooting the four-minute video for her newest single, "Make Me Like You," during a commercial break airing during the awards show. "It is such an amazing opportunity to do like live art," Stefani told ET. "I've never done anything like this before."

Celebrity Interactions to Keep an Eye On: Just when we thought everything was cool between Kanye West and Taylor Swift, the rapper dropped his latest album, The Life of Pablo, earlier this week, referencing the "Bad Blood" singer on one of his tracks: "I feel like me and Taylor might still have sex, I made that b**ch famous." Since its release, West claims Swift thought it was "funny," while she says she told him it was "misogynistic." Regardless of who's right, we're curious to see if the two will come face to face and what the end result will be.
